It is also possible to compile NRG Ljubljana using the EasyBuild framework. Using EasyBuild, NRG Ljubljana can be fully built (including taking care of all dependencies except Mathematica) using the command eb --from-pr 4651. The easyconfig is available here. (Version 2.4.3.23)
A Docker container is available. Pull using docker pull rokzitko/nrg. (Version 2.4.3.31)
And there is a Singularity container as well. (Version 2.4.3.31) Singularity itself can be obtained here. Installation instructions for Linux, MacOS, and Windows. Install packages for Debian and Ubuntu.
You might need a stand-alone NRG initialization code (Version 2.4.3.31). For testing, here are three examples for performing a simple calculation using either a locally compiled NRG Ljubljana, the Singularity version, and the Docker version. The Docker version has been tested to work on Linux and MacOS operating systems.
